TDS & TCS Compliance: Rates, Returns, and Common Pitfalls

Tax Deducted at Source (TDS) and Tax Collected at Source (TCS) form the backbone of India's tax collection machinery. Between them, they account for a significant share of direct tax revenue — and they are also responsible for a disproportionate share of compliance notices, interest demands, and penalty proceedings. In over a decade of practice, I have seen businesses lose lakhs in avoidable interest simply because someone applied the wrong section code or missed a quarterly filing deadline by a few days.

This guide covers every critical aspect of TDS and TCS compliance: the sections you must know, the rates that apply, the forms you must file, and the consequences you must avoid. Whether you are a business owner, an accounts team member, or a fellow professional, this is meant to be the reference you keep coming back to.

1. What Is TDS and TCS?

Tax Deducted at Source (TDS)

TDS is a mechanism where the payer (deductor) deducts tax at a prescribed rate from certain payments — salary, interest, rent, professional fees, contractor payments, and others — before crediting the amount to the payee. The deductor then deposits this tax with the government on behalf of the payee.

The obligation lies squarely on the deductor. If you fail to deduct, or deduct but fail to deposit, you are personally liable for the tax amount along with interest and penalties. The payee's tax liability does not change; it is the deductor who bears the compliance risk.

Tax Collected at Source (TCS)

TCS works in the opposite direction. Here, the seller (collector) collects tax at a prescribed rate from the buyer at the time of sale of specified goods or receipt of payment. The seller then remits this collected amount to the government. TCS applies to specific categories — sale of goods exceeding certain thresholds, scrap, minerals, motor vehicles above a specified value, and others.

The fundamental distinction: in TDS, the payer deducts tax before making a payment. In TCS, the seller collects tax in addition to the sale price. Both are advance tax collection mechanisms, but the obligation falls on different parties.

2. Key TDS Sections Every Deductor Must Know

The Income Tax Act prescribes TDS provisions across dozens of sections. The following are the ones that affect the largest number of businesses and professionals:

Section 192 — Salary

Every employer paying salary is required to deduct TDS at the applicable slab rates of the employee. This is computed on estimated annual income after allowing declared deductions (under Chapter VI-A), HRA exemptions, and other permissible claims. The employer must also consider the tax regime (old vs new) chosen by the employee at the beginning of the financial year.

Section 194A — Interest Other Than Securities

Banks, NBFCs, co-operative societies, and other entities paying interest on deposits or loans must deduct TDS at 10% when the aggregate interest exceeds the prescribed threshold in a financial year. For senior citizens, the threshold is higher. If the payee does not furnish a PAN, the rate jumps to 20%.

Section 194C — Payments to Contractors

Any payment to a contractor or sub-contractor for carrying out work (including supply of labour) attracts TDS at 1% for individuals and HUFs, and 2% for others. The threshold is Rs 30,000 per single payment or Rs 1,00,000 in aggregate during the financial year. This is one of the most frequently used sections and also the most frequently misapplied — particularly regarding the distinction between a "contract for work" and a "contract for sale."

Section 194H — Commission or Brokerage

Commission, brokerage, or any similar payment (excluding insurance commission) is subject to TDS at 5% when it exceeds Rs 15,000 in a financial year. This applies to distributors, agents, and intermediaries. Many businesses overlook this when paying trade margins to channel partners.

Section 194I — Rent

Rent payments exceeding Rs 2,40,000 per annum attract TDS at 2% for plant, machinery, and equipment, and 10% for land, building, furniture, or fittings. The deductor must hold a TAN and file quarterly returns. This is applicable to all entities — companies, firms, individuals, and HUFs — subject to the threshold.

Section 194J — Professional or Technical Fees

Fees for professional services, technical services, royalty, or remuneration to directors attract TDS at 10% (2% in case of fees for technical services other than professional services, effective from AY 2021-22). The threshold is Rs 30,000 per annum. This covers payments to CAs, lawyers, doctors, architects, consultants, and IT service providers.

Section 194Q — Purchase of Goods

Introduced from 1 July 2021, this requires any buyer whose turnover exceeds Rs 10 crore in the preceding financial year to deduct TDS at 0.1% on purchase of goods from a resident seller, where the aggregate value of goods purchased exceeds Rs 50 lakh in a financial year. This section was introduced to widen the TDS net and is particularly relevant for trading businesses. Note that Section 194Q does not apply if the transaction is already covered under TCS provisions of Section 206C(1H).

3. TCS Under Section 206C

Tax Collected at Source operates under Section 206C of the Income Tax Act. While TCS originally applied to a narrow set of transactions — sale of scrap, timber, minerals, tendu leaves — the scope has expanded significantly in recent years.

Section 206C(1H) — Sale of Goods

A seller whose turnover exceeds Rs 10 crore in the preceding financial year must collect TCS at 0.1% on sale of goods to any buyer where the aggregate sale consideration exceeds Rs 50 lakh in a financial year. This applies to all goods except those already covered under other TCS sub-sections and where the buyer is liable to deduct TDS under Section 194Q. The interplay between 194Q and 206C(1H) requires careful analysis — as a general rule, TDS under 194Q takes precedence when the buyer meets the turnover threshold.

Other Notable TCS Provisions

• Motor vehicles exceeding Rs 10 lakh — TCS at 1%
• Overseas remittance under LRS — TCS at 5% (20% for non-educational, non-medical purposes exceeding Rs 7 lakh)
• Overseas tour packages — TCS at 5% (20% above Rs 7 lakh)
• Sale of scrap — TCS at 1%
• Sale of minerals (coal, lignite, iron ore) — TCS at 1%

4. TDS Rates: Residents vs NRIs

TDS rates differ significantly based on the residential status of the payee. Payments to Non-Resident Indians (NRIs) are governed by Sections 195, 196A, 196B, 196C, and 196D, and the rates are generally higher:

• Interest paid to NRI — 20% (plus surcharge and cess) under Section 195, unless the DTAA provides a lower rate
• Royalty and technical fees to NRI — 10% under Section 115A (subject to DTAA)
• Long-term capital gains on listed securities — 10% under Section 112A (for NRIs)
• Sale of immovable property by NRI — 20% on LTCG, 30% on STCG (TDS at applicable rate on full consideration unless a lower deduction certificate is obtained)

For residents, TDS rates typically range from 1% to 10% depending on the nature of payment. However, if the payee fails to furnish a valid PAN, the rate escalates to 20% under Section 206AA. For non-filers of income tax returns (specified persons under Section 206AB), TDS is deducted at the higher of: twice the prescribed rate, twice the rate in force, or 5%.

Always verify the payee's PAN and return filing status before processing payments. The Section 206AB compliance check is available on the Income Tax portal and should be part of every deductor's standard operating procedure.

5. Quarterly Return Forms and Filing Deadlines

TDS and TCS returns are filed quarterly using the following forms:

• Form 24Q — TDS on salary payments (Section 192). This form has two annexures: Annexure I contains deductee-wise breakup of salary, and Annexure II (filed only in Q4) contains the detailed salary computation for each employee.
• Form 26Q — TDS on all non-salary payments to residents (Sections 194A, 194C, 194H, 194I, 194J, 194Q, and others). This is the most commonly filed return for businesses.
• Form 27Q — TDS on payments to Non-Residents and foreign companies (Section 195 and related sections). Requires additional details like the country of the payee, DTAA article invoked, and nature of remittance.
• Form 27EQ — TCS returns filed by collectors under Section 206C.

Filing Deadlines

The due dates for quarterly TDS/TCS return filing are:

• Q1 (April to June) — 31 July
• Q2 (July to September) — 31 October
• Q3 (October to December) — 31 January
• Q4 (January to March) — 31 May

Late filing attracts a fee of Rs 200 per day under Section 234E, subject to a maximum equal to the total TDS/TCS amount. Additionally, the Assessing Officer may levy a penalty ranging from Rs 10,000 to Rs 1,00,000 under Section 271H if returns are not filed within one year of the due date.

6. TDS Payment Due Dates

TDS deducted during any month must be deposited with the government by the 7th of the following month. The only exception is for the month of March: TDS deducted in March must be deposited by 30th April.

• TDS deducted in April — due by 7th May
• TDS deducted in November — due by 7th December
• TDS deducted in March — due by 30th April

For TCS, the same timelines apply. Government deductors have slightly different rules — they can deposit TDS on the same day without using a challan, through book entry adjustments.

Delayed payment attracts interest at 1.5% per month (or part of a month) from the date of deduction to the date of actual payment under Section 201(1A). This interest is calculated on a month-to-month basis, not on a daily basis — even a one-day delay into the next month counts as a full month of interest.

7. Lower and Nil Deduction Certificates (Section 197)

When the payee's estimated total income for the year results in nil or lower tax liability than what would be deducted at source, the payee can apply for a Lower Deduction Certificate or Nil Deduction Certificate from the Assessing Officer under Section 197.

The application is filed in Form 13 through the TRACES portal. If approved, the Assessing Officer issues a certificate specifying the rate at which TDS should be deducted (which may be zero). The deductor must then apply this reduced rate for the duration specified in the certificate.

This mechanism is particularly useful for:

• Contractors and professionals whose income after expenses falls below the taxable threshold
• Entities with significant brought-forward losses or deductions
• NRIs selling property in India — where without this certificate, TDS at 20% on the full sale consideration (not just the capital gain) creates a severe cash flow problem
• Businesses with thin margins where TDS on gross receipts far exceeds actual tax liability

A Lower Deduction Certificate is one of the most underutilised provisions in the Act. If your clients are complaining about excess TDS reducing their working capital, advise them to apply for a Section 197 certificate early in the financial year. Processing typically takes 15 to 30 days.

8. TDS on Property Purchase and Rent by Individuals

Section 194-IA — TDS on Purchase of Immovable Property

Any buyer purchasing immovable property (other than agricultural land) valued at Rs 50 lakh or more must deduct TDS at 1% of the total sale consideration. This applies even to individuals and HUFs who do not hold a TAN. The buyer must obtain a TAN, deduct TDS, and deposit it using Form 26QB within 30 days from the end of the month in which the deduction is made.

Important nuances:

• The threshold of Rs 50 lakh applies to the total consideration, including stamp duty value
• In case of joint buyers, each buyer must file a separate Form 26QB for their proportionate share
• The buyer must issue Form 16B to the seller within 15 days of filing Form 26QB
• Failure to deduct attracts interest at 1% per month under Section 201(1A)(i)

Section 194-IB — TDS on Rent by Individuals and HUFs

Individuals and HUFs who are not subject to tax audit but pay monthly rent exceeding Rs 50,000 must deduct TDS at 5% on the rent. Unlike other TDS provisions, the deductor here does not need a TAN. The deduction is made in the last month of the tenancy or the last month of the financial year, whichever is earlier. The deposit is made using Form 26QC within 30 days from the end of the month of deduction.

9. Consequences of Non-Compliance

The Income Tax Act treats TDS defaults seriously. The consequences are layered and cumulative:

Interest Under Section 201(1A)

• Failure to deduct TDS — interest at 1% per month (or part of month) from the date on which TDS was deductible to the date of actual deduction
• Failure to deposit TDS after deduction — interest at 1.5% per month (or part of month) from the date of deduction to the date of actual payment

Penalty Under Section 271C

If a deductor fails to deduct TDS (wholly or partly), the Assessing Officer may levy a penalty equal to the amount of TDS that was not deducted. This is in addition to the interest under Section 201(1A). However, this penalty cannot be imposed if the deductor proves there was a reasonable cause for the failure.

Prosecution Under Section 276B

This is the most severe consequence. If a deductor deducts TDS but fails to deposit it with the government within the prescribed time, criminal prosecution can be initiated. The punishment is rigorous imprisonment ranging from 3 months to 7 years, along with a fine. This provision is actively used by the department, particularly in cases involving large amounts or repeated defaults.

Disallowance of Expenditure

Under Section 40(a)(ia), if TDS is not deducted or, after deduction, is not deposited before the due date of filing the income tax return, 30% of the expenditure is disallowed while computing business income. This effectively increases the deductor's taxable income and can result in a significantly higher tax outgo.

10. Common Mistakes That Trigger Notices

Based on the TDS correction statements and demand notices I deal with every quarter, these are the most frequent errors:

• Applying the wrong section code — deducting under 194J when 194C is applicable, or vice versa. The distinction between "professional services" and "contract for work" is nuanced, and getting it wrong changes the rate from 2% to 10%.
• Incorrect or invalid PAN of the deductee — this results in TDS at 20% instead of the prescribed rate, and generates mismatches in the deductee's Form 26AS. It also creates demand notices that take quarters to resolve.
• Late payment of TDS — even one day late attracts 1.5% per month interest. For a Rs 10 lakh TDS payment delayed by one day into the next month, the interest is Rs 15,000.
• Not filing a nil return — if you hold a TAN but had no TDS transactions in a quarter, you are still expected to file a nil return. Not filing leads to demand notices under Section 234E.
• Mismatch between TDS deposited and TDS claimed in returns — this happens when challans are not properly mapped or when correction statements are pending.
• Ignoring Section 206AB verification — failing to check whether the deductee has filed their income tax return for the preceding two years. If the deductee is a "specified person," TDS must be deducted at the higher rate.
• Not issuing TDS certificates on time — Form 16 must be issued by 15 June, Form 16A within 15 days from the due date of filing the quarterly return.

11. Practical Tips for Smooth Compliance

After handling TDS compliance for hundreds of businesses, here is what separates those who never receive notices from those who are perpetually firefighting:

• Maintain a TDS calendar — mark the 7th of every month for payment and the quarterly due dates for return filing. Set reminders at least three days in advance.
• Verify PAN before every payment — use the income tax portal's PAN verification facility. Do not rely on PANs provided verbally or on letterheads that may be outdated.
• Run the Section 206AB compliance check — the TRACES portal provides a bulk verification tool. Run this at the beginning of each quarter for all regular deductees.
• Reconcile Form 26AS with your books quarterly — any mismatch should be corrected before filing the next quarter's return. Correction statements become exponentially more difficult to file as time passes.
• Keep deduction documentation organized — maintain copies of lower deduction certificates, Form 15G/15H declarations, PAN cards, and DTAA-related documentation. These will be your defence in any assessment proceeding.
• Use TRACES for challan corrections — minor errors in challans (wrong assessment year, minor amount, wrong section code) can often be corrected online through TRACES without needing to visit the bank or the department.
• File correction statements promptly — if you discover an error in a filed return, do not wait. The TRACES system allows online corrections for most types of errors, and filing them quickly prevents cascading issues in subsequent quarters.
• Engage a professional for complex situations — NRI payments, cross-border transactions, DTAA applicability, Section 195 certificates, and multi-state deductions are areas where getting professional advice upfront costs far less than resolving notices later.

TDS compliance is not difficult — it is unforgiving. The rules are straightforward, the deadlines are fixed, and the penalties are automatic. The businesses that stay compliant are not the ones with the best tax knowledge; they are the ones with the best systems and discipline.
